So yes there IS a roan gene and it IS testable. There are also MULTIPLE strains of both dominant white and sabino that have no current tests, just like rabicano does not have a test.
I already looked at that site and though it recognises a dominant gene - ie - a roan horse will usually produce a roan horse (as is the case with roan coloured Clydes) it hasnt yet recognised the specific mutation that causes the roan colour so there is no direct test for the gene.
According to that report DNA markers have been identified in Paints and Quarter Horses associated with roan colouring but it doesnt mention if any other breeds have even been tested yet.
Until more tests have been done to identify other strains of White and Sabino they can't be ruled out or accepted
There have been many incorrect articles published on the internet so its not always easy to know which are to be believed
The UK does have its own genetic testing facilities but mostly breeders/owners are only interested in genetic disorders - mainly I suppose because we are happy with our traditional colour descriptions as it really makes no difference to the quality of the horse

If that's the case then this horses colour may have nothing to do with genes and all to do with its breed characteristics - oh and arent they also genetic?
You can't possible tell what the colour genes are anyway from looking at a photograph so the whole thing is irrelevant really.
Why try to create an argument and bad feeling from something so petty?
Actually... I could be wrong on this, but to me that looks like a sabino. So did the horse that you showed under saddle. I'm not saying I'm right and you're wrong, I'm just saying that's what I see

What we see and what is actual aren't the same thing. I made the comment per many horses that are described as roan and look like roan are actually grey - one way to verify this is that roans do not lighten with age whereas a grey does, also the dappling you see on greys has the larger light circle inside the dark ring but in roans that often have a dappled appearance its the other way around.
He may look like sabino but according to the tests done on Clydes they do not test positive for this gene - however as already said so far only the sabino1 gene has been identified for testing purposes so there may be more sitting there waiting for discovery - funding is the main issue for lack of progress in colour genetics as many people don't regard breeding for a specific colour as important - in fact many see it as detrimental to the more important 'breeding for conformation and performance' criteria and its people paying for tests and donations etc that further scientific work like this.

I know it's not grey, but it doesn't strike me as roan either

Its a shame that the ad has now been removed as we could have all clubbed together and asked for some samples to send off for testing!!!
